(R)-STU104 is a potent and orally active TAK1-MKK3 interaction inhibitor with IC50s of 0.58 μM and 4.0 μM for TNF-α and MKK3 phosphorylation. (R)-STU104 suppresses the TAK1/MKK3/p38/MnK1/MK2/elF4E signal pathways through binding with MKK3 and disrupting the TAK1 phosphorylating MKK3. (R)-STU104 can be used for researching ulcerative colitis.

Description

(R)-STU104 is a potent and orally active TAK1-MKK3 interaction inhibitor with IC50s of 0.58 μM and 4.0 μM for TNF-α and MKK3 phosphorylation. (R)-STU104 suppresses the TAK1/MKK3/p38/MnK1/MK2/elF4E signal pathways through binding with MKK3 and disrupting the TAK1 phosphorylating MKK3. (R)-STU104 can be used for researching ulcerative colitis[1].

IC50 & Target

IC50: 0.58 μM (TNF-α), 4.0 μM (MKK3 phosphorylation)[1]
In Vitro

(R)-STU104 attenuates phosphorylation levels of Mnk1, MK2, and elF4E, leading to the downregulation of TNF-α expression and production[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
